# How to Grade Loft Loss in a Used Down Puffer Before You List It

_By GradeThread Team · Published November 1, 2026_

> A puffer can look spotless and still be flat. Here is the fill recovery, baffle, and shell test that sets the tier before a buyer finds the cold spots.

To grade loft loss in a used down puffer, compress the jacket, release it, and time how fast the baffles rebound, then check for clumps, bare spots, and shell wear. Full, even recovery in a few seconds supports Excellent. Slow recovery, flat patches, or clumping drops it to Very Good or Good.

Here is the return we see most with down. A seller lists a black puffer as Excellent because the shell is clean and the zipper runs. The buyer pulls it out of the box, and the chest is full but the lower baffles are flat and the sleeves are thin. Message: "Not as described, it's not warm." The jacket was clean. It was not Excellent. This guide gives you a repeatable test so the grade holds up.

## Why loft loss decides the tier on a down puffer

A puffer is sold on warmth, and warmth comes from loft. Loft is the trapped air between down clusters. When clusters clump, break down, or migrate, the jacket loses insulating power even if nothing looks wrong from across the room.

In our five factors, loft loss touches three at once:

- **Structural Integrity:** baffle seams, stitch-through lines, and fill distribution.
- **Fabric Condition:** shell thinning, abrasion, and any feather leakage through the fabric.
- **Odor & Cleanliness:** damp, musty, or body-oil smell that sits in the fill.

Cosmetic Appearance and Functional Elements matter too (stains, zipper, snaps), but a flat jacket with a perfect zipper is still a flat jacket. Buyers of puffers are often buying for cold weather, so a loft problem is a function problem in their eyes.

## What you need before you start

Keep it simple. You need a flat table, a bright window or a raking light, a tape measure, and a clean, dry jacket. Test the jacket dry. Damp down looks flat and clumped even when it is healthy, so if the jacket has been stored in a bag or just washed, let it dry fully and fluff it first. If it has been stored compressed for months, give it a day hanging before you judge it. Otherwise you are grading the storage, not the fill.

## The five-step loft loss test

1. **Hang it and look at the silhouette.** Zip it and hang it on a wide hanger. Even, rounded baffles from collar to hem are what you want. Note any rows that sag, any collapsed sleeves, or a hem that has lost its shape.
2. **Run the compression and recovery test.** Press a flat hand into the chest baffles, hold for five seconds, and release. Healthy down rebounds within a few seconds and looks full. Slow, partial rebound means worn or damp fill. Repeat on the sleeves and lower body, since these lose loft first.
3. **Hunt for clumps and cold spots.** Hold the jacket up to a window or shine a light through each baffle. Clusters of down look like small lumps. Bare areas look translucent. Squeeze each baffle gently and feel for hard knots or empty pockets.
4. **Check baffle integrity and seams.** Look along every stitch-through line for open stitches, pulled threads, or down poking through. Tug gently at a seam. A baffle that has split lets fill migrate and cannot be fixed by fluffing.
5. **Inspect the shell for wear and leakage.** Run a hand over the shell at the cuffs, hem, elbows, and shoulders where straps and friction hit. Look for thin, shiny, or scuffed patches, small tears, and feather quills poking out. Check for stains and odor, then rate each finding against the table below.

## Fill recovery: what the rebound tells you

You are not measuring fill power in a lab. You are judging relative recovery, and that is enough to grade. Compare the jacket with itself: the chest should recover about as fast as the back, and left and right sleeves should match. A big mismatch between zones usually means uneven wear, compression from a backpack, or migration.

Two common misreads to avoid:

- **Fresh from a wash:** clumped wet down looks ruined but often recovers fully once dry. Grade only after it is fluffed and dry.
- **Long compression:** a jacket crammed in a thrift bin may be flat but recover after a day. Hang it and retest before you call it loft loss.

If recovery stays slow after drying and fluffing, that is real loft loss, and it moves the grade. We do not guarantee any fill number from this test. Describe what you measured and saw, not a fill power you cannot verify.

## Baffle damage and shell wear: where the tier drops

Baffle and shell findings are where Excellent turns into Very Good or Good. Use this as a starting guide, then let the full report weigh all five factors.

| Finding | Likely effect | Typical tier |
| --- | --- | --- |
| Full, even rebound, intact seams, clean shell, no odor | No deduction | Excellent |
| Slightly slower rebound in sleeves only, light shell scuffing at cuffs | Minor Fabric Condition and Cosmetic Appearance deduction | Very Good |
| Visible flat zones in one or two baffles, a few small clumps, a patched pinhole | Structural Integrity and Fabric Condition deduction | Very Good to Good |
| Multiple flat baffles, down leaking at seams, thin shell at elbows | Significant Structural Integrity deduction | Good to Fair |
| Split baffles, large cold spots, torn shell, persistent odor | Major deductions across several factors | Fair or Poor |

NWT and NWOT puffers are rare on the secondhand side, and they carry a firm requirement: never worn, full loft, no compression marks. If you cannot prove that, grade it as used.

### A note on repairs

A tape patch or stitched repair on the shell does not erase an otherwise strong jacket, but it must be disclosed and it affects Cosmetic Appearance. A repaired tear on a high-wear zone like the forearm usually keeps the jacket from Excellent.

## Writing the listing so the grade holds

Once you have a tier, put the evidence into the listing. A single plain line often prevents the return. Compare these two:

- **Weak:** "Very warm, great condition, barely worn."
- **Strong:** "Full loft in chest and back; sleeves rebound slightly slower. Light scuffing on right cuff, one small patched pinhole on left hem (photo 7). Smoke-free, freshly laundered."

Shoot the defects. Add a backlit shot showing the baffles, a close shot of each repair, and a shot of the cuffs. On eBay, fill in the item specifics for insulation type and the condition description. On Poshmark and Mercari, assume buyers will counter with offers aimed at your most visible flaw, so show it first and price for the real tier. A Very Good puffer listed as Excellent invites a dispute. A Very Good puffer listed honestly sells without one.

## Grade one puffer before you list it

Pick the puffer sitting in your pile that looks best on the hanger. Run the five steps, note what you find, then compare your tier to what you were about to write. If you want a second read, grade it with GradeThread: you get a 1.0–10.0 grade, a report across the five factors, and a certificate buyers can verify. One garment is enough to see whether your eye and the report agree.
